There are 100 lockers, all closed. On the first pass you alter the state of all lockers (ie closed -> open; open -> closed). On the second you alter the state of every second locker, and so on until you make 100 passes. Which lockers remain open after?

1, 4, 9, 25, 36, 49, 64, 81, 100. A locker remains open in the end if it has an even number of factors. The only way for a number M to have an even number of factors is to be something squared, because otherwise a factor N can always be paired by M/N.
